Using C++

Write multiple programs that read a PGM image from file "inImage.pgm" and outputs a modified image to "outImage.pgm"

a. Write a prorgram that inverts all colors, so white becomes black and black becomes white

b. write a program that inverts the colors only in the right half of the picture

c. write a program that draws a white box exactly in the middle of the picture. the dimensions of the box should be 50% by 50% of the original pictures width and height

d. same as C, but it should be a frame exactly one pixel thick

e. Scale the original picture to 200% of its size, Can be done by increasing the size of the picture by the factor of 2, and copying each pixel of the input as a small 2x2 square in the output

f. pixealte the input image, so make every 2x2 non-overlapping window contain the same value (averaged over all the pixels in that window of the input)
